As if you want to stop spam bots from collecting emails on your public page - itβs very difficult to tell the difference between users and bots without forcing your viewers to log in to confirm their identity.
You can use robots.txt to prevent spiders that really follow these rules, but this is on their side, not on your server. There's a page that explains how to catch those that violate the rules and explicitly forbid them: Using Apache to Stop Bad Robots [evolt.org]
If you need an easy way to stop Dizzler, in particular using .htaccess, you should open it and add:
<Directory /directoryName/subDirectory> Order Allow,Deny Allow from all Deny from 66.232.150.219 </Directory>
